▎ 摘 要
NOVELTY - Lithium-sulfur battery anode material comprises anode active material, binder and conductive agent. The binder is modified polyacrylamide binder (I). USE - The lithium-sulfur battery anode material is useful in lithium-sulfur battery anode sheet and lithium-sulfur battery (all claimed). ADVANTAGE - The lithium-sulfur battery anode material: inhibits dissolution of polysulfides in electrolyte, improves utilization efficiency of sulfur elements, and discharge capacity of lithium-sulfur batteries, inhibits volume expansion and contraction and stress change of the anode material during the battery cycle. DETAILED DESCRIPTION - Lithium-sulfur battery anode material comprises anode active material, binder and conductive agent. The binder is modified polyacrylamide binder of formula (I). l, m, n = not defined; R1= unsaturated acid group including unsaturated carboxylic acid (acrylic acid, methacrylic acid, crotonic acid, maleic acid, fumaric acid and itaconic acid), unsaturated sulfonic acid (tert-butylacrylamide sulfonic acid, trimethylolpropane trimethacrylate and styrene sulfonic acid) and unsaturated phosphoric acid (ethylene bis2-(methacryloyloxy)ethylphosphate and bis2-(acryloyloxy)ethylphosphate); and R2= hydroxy group-containing group. INDEPENDENT CLAIMS are also included for: Lithium-sulfur battery anode sheet; and Lithium-sulfur battery.
